With the rapid development of our country’s aerospace industry, precision sheet metal parts are more increasingly used. According to different design and application requirements, aviation pipe parts have also been improved from the original free bulging process to various controllable bulging processes, which have greatly broaden the application range. One of the metal molding processes is internal high pressure bulging process, which is widely applied in aviation manufacturing fields. The difficulty form, multiple influencing factors and the complex process are always hard to resolve. In this study, an example of the aviation clamp part is investigated. Axial material compensation amounts, internal pressure and loading paths have been discussed. Through the numerical simulation analysis, the process parameters can be optimized, a simple high-pressure tube bulging process method has been successfully applied, which is beneficial to shorten production cycle and save production costs.
